Thanks for the credits Bob. I'm always glad the hear when someone starts enjoying the FRG-7 again.
This give me energy to go continue. Apart from the FRG-7, I'm also busy making a display for the RA17 and the Deltahet.

Sadly, its RAINING here in NZ today, so installed the new display..... If it rained more, I would be even happier.

Having fat fingers meant it was easier for me to remove the front plastic bezel/faceplate to better access the Smeter area from the front..... just the three knobs and 3 screws need be removed.? Be aware of the lock LED wires when moving the panel outwards.

The display? powered on immediately and works very well indeed.;? I did opt to power the display via the lighting circuit, this allows it to be switched off if the interference obscures a wanted signal. This is really the result of the always unhappy marriage with digital and analog circuits, and several birdies will be noticed as you tune the upper bands. These are spurs generated by the processor, and unless radical shielding measures are taken, its something to be tolerated.

This is a great addition to the FRG7.? ?

Thank you Marcel.

I did check WWV 10mhz and it was spot on.

Hi Bob,

How about accuracy checking against WWV on 10 MHz and 15 MHz and reporting the results?

I just finished installing this great digital display in my Sears version of the FRG-7.? Took about 1.5 hours and it works flawlessly just as designed. What a great update to this old reliable multi-band receiver.? Thanks Marcel.

Today the package arrived, awesome job by the postal system and our overworked customs. They are overworked because of our greedy government wanting all kinds of taxes from anything crossing our shores.

The kit is of very good quality, and is very compact, well packaged and thought out. Marcel has done a very good job with this, I hope many take the opportunity to buy one, that helps creators continue to create niche products that big companies would not bother with.

Tomorrow I hope to get time to install it into my FRG7, that can only happen if its raining, Im told the lawns need mowing............

Hi Steve, thanks for the compliments

Hi Randy,

?

Yes, that is the new version. But I can make you a better offer than on Ebay. The expenses at Ebay are rather high and I try to reduce the cost for the buyer.

Please contact me at pa8ma.radio@... if you are interested.

Regards, Marcel

Sorry, I thought the kit wasn’t available yet, but I think I see it on eBay. Is this the same one? Link: https://www.ebay.com/itm/145745777645

I’d like to buy a v2 kit as well!

This is a beautiful upgrade to a classic receiver. ?Great design!

Thank you Lex

The FRG-7 display is in production. For the RA-17 I would like to 3D-print the housing of the S-meter, with the display integraded.

Like with the FRG-7, it is my goal to bring it back to its original state within a half hour.

But it will take a while before this kit is ready.

That is awesome, I am sure these will be very popular. I want two when you are in production.? The display is likely a tad small given the bulk of the Racal RA17 front panel, I would envisage it being mounted externally . However, I am impressed very much with your design.

Nice modification,?

Hi,

?

In a previous post, I've announced that I was making a new kit for a digital readout with also a MHz indication.?

Now I've assembled the first PCB's and they function?well.

For an impression, look at

@Pentagrid, concerning your remarks about the RACAL RA-17. I'm in the lucky position to own one now.

I'm busy, finding the right points for the signals and the power supply. The kit will probably replace the S-meter.

For anyone who is interested, please contact me.

Best regards,

Hi,

?

I have my FRG-7 for sale.

?

It is an early version without the "fine tune" control.

?

It is in good condition for its age an works well.

?

I am looking for offers near ?150 and it will need to be collected from RG31 area of Reading, Berkshire UK.

?

Comes completed with original manual and circuit diagram.

Marcel, that is excellent work. Just a suggestion to increase the versatility of your design dramatically. As you know, the VCO frequency of the FRG 7 runs from 55 to? 85 mHz with a 55mHz 1st IF. The very common Racal R17 uses the same Wadley loop design, with slightly different VCO frequencies, this one spans 40 to 70 mHz with a 1st IF of 40 mHz.. IF you could find? a little room to program a few extra? bytes into the "megacycle" routine, a keypress perhaps to alter a pointer to a lookup table, this would increase interest enormously..... there are many Wadley loop receivers? out there.that are lacking a good readout, I think interest would be very high. I would buy two without question.

Hi Marcel,

It looks good and I am glad you got it working well. I am looking forward to buying one.

Hi Chris,

Coming back to your question concerning the MHz readout, it seems my proto is working well.

I could stay to the Arduino, but I had to squeeze everything out. I'm now at 99% of the memory.

I also switched to 7 segment characters. I've included some pictures.

Now I can start to design a new PCB. Hope to have it ready within a few months.
